128293-93-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128293-93-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,9 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128293-93:
(8*1)+(7*2)+(6*8)+(5*2)+(4*9)+(3*3)+(2*9)+(1*3)=146
146 % 10 = 6
So 128293-93-6 is a valid CAS Registry Number.

2-Aryl-1,2,3-thiadiazolium salts

Alekseenko,Bazhbeuk-Melikova,Zelenskaya,Kozinskii

, p. 1299 - 1300 (2007/10/02)

When arylhydrazones of α-methyleneketones are treated with thionyl chloride they form 2-aryl-1,2,3-thiadiazolium chlorides in high yield, via the intermediate 1,2,3-thiadiazol-3-ine 1-oxides. The effect of substituents on the course of the cyclization was investigated.
